WICK-BAISER FOR MINERS IAMPS.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed May 2B, 1908. Serial No. 436,510.

To all whom "it may concern.

Be it known that I, Louis P. EISENBEIs, a citizen of the United States, residing at Ottumwa, in the county of VVapello and State of Iowa, have invented new and useful Improvements in Wick-Baisers for Miners Lamps, of which the following is a specification.

My present invention relates to improvements in wick raisers for lamps especially of the type used by miners, and it has for its object primarily to provide an improved device of this character that is simple in construction so that it may be manufactured cheaply and is not liable to get out of order, and wherein the wick raiser is so mounted with respect to the wick tube that it will permit the introduction of a wick without interfering therewith, and which will not permit the oil to escape from the wick tube except at the top thereof at which point the flame is located.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

In the accompanying drawing: Figure l is a perspective view of a miners lamp equipped with a wick raiser constructed in accordance with my present invention, a portion of the wick tube being broken away to illustrate the wick raiser; Fig. 2 is a plan view of the lamp shown in Fig. l; Fig. re resents a vertical section of the wick tu e; Fig. 4 represents a transverse section of the wick tube as shown in Fig. 3; Fig. 5 is a perspective view of the inner wick tube constructed to receive the wick raiser; and Fig. 6 is a perspective view of the wick raiser removed from the tube.

Similar parts are designated by the same reference characters in the several views.

Wick raisers constructed in accordance with my present invention are capable of being readily applied generally to miners lamps of various constructions. In the accompanying drawing, I have shown the invention applied to an ordinary miners lamp having an inner wick tube and a surrounding coolin tube. It will be understood, however, t at the drawing illustrates one specific embodiment only of the invention, and that certain changes in the specific construction or modifications in the relative arrangements of the parts, may be made in order that the invention may be applied to the best advantage in each particular case.

In the present instance, the lamp to which the invention is applied comprises a body portion or receptaclel which is adapted to contain a suitable quantity of oil, it being provided with the usual top 2 and a supporting hook 3. Attached to the body portion of the lamp is a wick tube 4 and, if so desired, an outer tube 5 may be provided which sur rounds the wick tube and provides an annular cooling space. It is obvious, however, that this outer tube may, if preferred, be omitted. The Wick tube is formed with a longitudinal or axially extending groove or channel 6 which extends from the top of the tube downwardly to a given point, the groove or channel in the present instance eing formed integrally with the wick tube by crimping or rol in a portion of one of its walls into substantial y the form of a second smaller tube, and by forming this groove or channel integrally with the wick tube, the use of rivets or of solder which would be liable to melt, is obviated. The lower end of this roove or channel merges into an outward Y expanded portion 7 which is also preferably formed integrally with the wick tube and is of segmental form so as to partially surround the tube, this outwardly expanded portion being of such a length with respect to the axis or length of the tube as to permit a suiiicient longitudinal movement of the 'wick raiser. This wick raiser' shown in the present instance is composed of a wire which is doubled longitudinall so as to form an intermediate ortion 8 which is adapted to extend over t e upper edge of the outer tube 5, and the ends of the intermediate portion form a pair of substantially parallel arms 9 and 10, the arm 9 being adapted to enter the lon itudinal groove or channel 6 of the wick tu e and is provided on its lower end with a laterally bent segmental wick engaging jaw 11 which is adapted to enter the outwardly expanded portion 7 of the wick tube and to operate longitudinally therein as the wick raiser is elevated or lowered. The other arm 10 of the wick raiser extends downwardly at the outer side of the tube 5 and is preferably provided at its lower end with a rolled ortion or other suitably formed part which is adapted to provide a handle 12 by means of which the wick raiser may be readily manipulated. The wick engaging jaw ll of the wick raiser is preferably serrated or provided with relatively sharp teeth at its inner side, as shown, whereby it may obtain an effective hold upon that portion of the wick with which it engages.

Normally, the curved or segmental jaw of the wick raiser occupies a position within the outwardly expanded portion 7 of the wick tube, the inner or serrated surface of this jaw lying substantially Hush with the interior bore of the wick tube, as shown in Figs. 1, 3 and et. lhile the wick raiser is in this position, a wick may be readily inserted into the wick tube from either end, preferably from the lower end. After the wick tube has been inserted, the wick may be raised from time to time as occasion may require by first turning the wick raiser by means of the handle 12 so as to rotate it about the arm 9 as an axis, the groove or channel 6 serving as a bearing. Such a rotation of the wick raiser will move the serrated jaw 11 thereof inwardly thereby obtaining an effective hold upon the wick, and while the wick raiser is held in this position, it is elevated, such a movement of the wick raiser causing the wick to be fed toward the upper end of the wick tube, and when it is desirable to again raise the wick, the wick raiser is rotated so as to carry the serrated aw thereof into the outwardly expanded portion 7 of the wick tube, and while it is thus contained in this portion of the wick tube, the wick raiser may be depressed, thereby passing the wick freely and without engaging it so as not to carr the wick downwardly. After the wick ralser has been sufiiciently lowered, it may then be rotated so as to carry the serrated jaw again into engagement with the wick, and by lifting the wick raiser while the edge thereof is thus en aged with the Wick, the latter may be su ciently raised. In the present instance, the wick tube, as previously stated, is surrounded by an outer tube which serves not only to effect a cooling of the wick tube, but it also conceals the outwardly projecting groove or channel and the expanded portion into which said channel leads so that the lamp presents a neat appearance. It will be obvious, however, that this outer tube may, if so desired, be omitted, in which case the wick tube and its cooperating raiser will be complete in itself. As the groove or channel'and the outwardly expanded portion which receive the Wick raiser are formed integrally with the wick tube and do not perforate the same, it Will be obvious that leakage of oil below the top of the wick tube is impossible.

A wick raiser constructed in accordance with my present invention is simple in construction and may be manufactured cheaply, and by applying it to the Wick tube in the manner shown, 1t is possible to readily form the wick tube so as to aceon'ln'iodate the wick raiser with the greatest facility, the ou(- wardly projecting channel and expanded portion being preferably formed by means of dies so that the manufacture of these parts is inexpensive, and in practice, the wick raiser serves to eiiiectually raise the wick from time to time as may be necessary. lv'loreover, b v al'iplyiner it to the wick tube in the manner hercinbe Vore described, leakage of oil is eti'ectually fn'evented, and the necessity of attaching additional parte to the wick tube, such for instance as by rivets or soldering, is obviated.
